Use them by marking the workpiece before heating begins.
TEMPIL TEMPERATURE INDICATOR
STICKS
CON-TROL-CURE¢ç Tempil Indicator Sticks are ideal for working below 700¡ÆF
on relatively rough surfaces where prolonged heating is not required. Indicator
Sticks are suitable for determining surface
temperatures during preheat, annealing and stress relieving processes. Use
them by marking the workpiece before heating begins. The blunt-tip crayon's
dry, opaque mark will change to a distinct melted mark when the temperature
rating of the selected Temperature Indicator Stick is reached.
Available in temperature ratings with melting points of 109, 119, 125, 131,
144, 150, 163, 175, 188, and 200¡ÆF. Other temperature ratings with melting
points from 100-2500¡ÆF can be special ordered, minimum 10.
